To all whom it may concern Be it known that l, lPAUL l DEGENKOLB, a citiien of the United States, residing at Itasca, in the county of Dupage' and State of Illinois, have invented certain new and useful Improvements in llipers far Windshields and the like, of which the following is a specification.

This invention. relates to a wiper designed particularly for use on the wind shield of an. automobile, although its application to other uses is also contemplated. Among the general objects and advantages realized by this invention are relatively low cost of manufacture, ready application to either side of an automobile wind shield; adaptability to functionl under conditions when the two windows of the shield are in angular relation to each other; and in general freedom from vibration, reversibility in operation, etc. These and other-objects are incidents of my inventioinan exemplifiestion of which is illustrated on the accompanying drawings in the gnanner following:

Figure 1 is a view in perspective of part of an automobile, exhibiting a wind shield to which is applied the present device;

Fig. 2 is a side elevation of the wiper per se; i

. Fig. 3 is an edge View thereof, the handle being shown in the background;

Fig. 4.- is a transverse section through the device taken on line 4-4 of Fig. 2;

Fig. 5 is a similar View on line 5--5 of Fig. 2; and Fig. 6 is a transverse section taken through a wind shield showing its two windows in angular relation with the wiper operatively positioned against each.

As already stated, the present device ,is adapted fol-wiping windows generally, but is espec1ally suited for use with the wind ,A shield of an automobile such as is represented in Fig. 1, wherein 1S shown a frame 10 'havlng upper and lower windows 11 and 12 respectively, each adapted to be tilted within the frame in the usual manner, the

two adjoining edges ofthe windows being slightly spaced apart as at 14.

The wiper includes in its construction a longitudinal frame A, preferably of sheet metal that is bent to provide a U-shaped cross section, with spaced sides 15 and 16 Specification of Letters Patent.

connected by relatively narrow webs 1'? one at each'end, and by a central web 18. tween these webs there is an open space, as best indicated in Fig. 3. A handle is cured to the frame preferably'by means of a shanlr 20 havi one end bent to form an eye which encircles a pin 21 that is secured transversely between the two walls 15 and iii":

16 adjacent the web 18. This shank is entended through the axial bore ofthe handle and carries at its extremity a button 23 to which it is connected'as by means of screw threads desired, the axial bore of the handle may be provided with one or more radial slots 25 to receive in each a flu or wing 28 which projects laterally from. the shanlrQO so to establish rotative continuity between itself and the handle. linteriorly of the handle there is also provided an enlarged chamber 27 within which is re ceived a coiled spring 28 one end of which abuts against t is chamber end 23', and the other against the button 1.23, the client bein to normally hold the frame tight against the proximate end of the handle. it is preferred that cushion of pad SObe carried on Y the handle end which is ad acent the frame;

C each formed alike and each reversible 'to present either of two w1p1ng surfaces operatively to the window. These wipers may comprise in each instance a core 31 in the form of a plate around which placed a tubing of rubber or some other appropriate wiping material, the tubing being normally stretched over the core plateso as to remain J tightly thereupon. Each plate and tubing is substantially of the same length and is designed to occupy practically the entire space between the central .web webs .17. Each wiper niay, furthermore, be securedin place as by means of .a pin 33 which extends tran versely between the two walls 15. and 16 through the mid point of the wiper per mittting it to swing around within the frame, itdesired, so asto present either of its wiping edges tothe window.

The ends of the pins 33 are preferably in flush relation with the frame A. Ac

cording to this construction, the frame may be formed relatively narrow so as to enter into the gap 14 which usually exists between the two Windows ll and 12 of as wind shield, '5 necessary this gap may be further increased by moving one Window angulerly of the other.

in use the device is positioned as shown in Fig. 1, being .slippedinto place through the gap 14% to present the frame A with its two wipers to one side of the Window, the handle B remaining on the opposite side thereof. Positioning of the device is facilitated by a pressure of the thumb upon the button 23 15 which causes the frame to recede from the handle B suiiiciently to permit the frame to lie to one side of the Wind shield and the handle to the other (see (3). By rototing the handle, "the device may be positioned so vertically, as shown, following which it is ready for horizontal movements to effect at wiping of bothwindows at once, the shank traversing the gap 1% during these opera tions. lit the Windows be engulerlydisposed to each other (1S suggested by full lines in Fig". 6, the two Wipers will auto erratically slime themselves to Wipe both Windows at once, or if these windows be oppositeiy inclined, as represented by the dot- 36 ted lines, the Wipers will then assume a similer angle.

The device may be readily withdrawn" from operative position upon being; given a quarter turn to permit withdrawal through the gap 14 whereupon the reverse edge of the wipers becomes effective to en gage with the interiorsurface oi the wind shield. lit either wiping edge becomes worn out or otherwise unfit for use, the wiper may all) be reversed to present its opposite ed e,

thereby conducing to long service. The suggested construction of Wiper by which a, tubing is stretched over a core plate is advantageous in many Ways, but may'obviously is be modified ifsome other construction be preferred. Also in other particulars the device may be changed or modified Without departing from the'spirit of this invention a as defined by the appended claims. u I claim:
